The closed analytic result for the single massive integral was first used
in Ref. [1]} for the calculation of subtraction terms in QCD jet cross sections
at NNLO and more recently in Ref. [2]} for subtraction terms in Higgs production.
The single massive integral found further application in Ref. [3]} to pin down
phase space master integrals. Also the N\(^3\) LO study of Higgs production
in Ref. [4]} employed Somogyi's new results. A brought discussion of techniques
for phase-space calculations, emphasizing the benefits of a rotational invariant approach based on
Somogyi's methods, is given in Ref. [5]}. Ref. [6]}
on the Drell-Yan process at N\(^3\) LO involves both the Neerven integral and Somogyis findings
in the determination of phase space integrals in the soft region. Furthermore angular integrals
in the Somogyi parametrization make their appearance in the determination of beam and soft functions
(see Ref. [7]}).
